Directional random scattering MIMO channels: Entropy analysis and capacity optimization

Sadeghi, Parastoo; Kennedy, Rodney; Abhayapala, Thushara


In this paper, we study the effect of directional random scattering on the capacity of multiple-input multiple-output (MIMO) systems. First, we use the spatial decomposition of the MIMO channel matrix to analyze the randomness (entropy) of directional scattering. The analysis shows that directional scatterers (with at least a null in the angular power spectrum) will no longer be random when the receiver observation radius is sufficiently large. Therefore, directional scattering limits the...[Show more]
